Very comfortable with good lower-back support
Most comfortable, well made, easy assembly office-gaming chair (very pleased)! *I suggest, HOLD-OFF popping the seat onto the upper-cylinder until AFTER assembling the back-rest onto the seat/arm-seat with back-rest as a unit...can then be popped onto the upper gas-cylinder(Much more stable than fighting with chair freely rolling and turning) while attempting to aligning the holes assembling the back-rest. Afterwards the seat with back-rest assembled can easily be popped onto to the upper-end of the gas-cylinder and we are good to go! * do pay attention to using the correct bubble-packed bolts for each assembly, as directed * all the holes align -up very precisely... so if screwing in the bolt(s) and after a couple-turns it gets hard-to-turn, we are 'cross-threading the bolt into the threaded hole...so back-out and realign the bolt as so it threads in very easy. * the bubble-pack of bolts are clearly labeled so as we easily know which ones go where. *0ne bubble-packet even includes a spare group just in case we lost one (like out in the grass-lawn)? * Included a T-handle alien-head wrench (all needed for total assembly) very nice for having around if any re-tightening needed. all speaks Quality! >>> Been using about a month now...And I REALLY like this office gaming chair _ very comfortable cushioned well and excellent lower-back support _ the faux-leather seems to be more thick and durable and stitching is NOT ripping-out (as my previous & more expensive chair had done with it's paper-thin faux leather) _ easy assembled chair seems very sturdy and solid, (yet light weight), in moving around, (not some wobbly contraption as my previous more expensive chair). _ a strong Five-Star rating!

nice chair for the money
This is a great chair for those not wanting to spend a lot of money and well built and sturdy. I don't do gaming so I'm looking at it as a computer chair so that's what my review will focus on. I had no trouble putting it together as it has a nice instruction book and not a one page print out like most China made products. Also the enclosed Allan wrench with a handle was someone's smart idea. It looks good (I also bought it since it was red) it's comfortable and fit's my needs but I can't comment on the durability factor as I have it for just a few days but I have no complaints for the price I paid at this time.

I Recommend!
very comfortable chair ive had it for a while now, it starts to get a faint creaking noise, but nothing unbearable. the cushions are firm yet comfortable at the same time. its not too big of a chair, fits great in my room. for the price , its pretty good quality, same could be said for its reclining, depending on how you set the tension of the reclining, the chair can be reclined with ease, or tight. this chair was easy to use and to set up. I very much recommend.

Great chair at a great price point.
This item was easy to put together, it was comfortable and visually stunning to look at. My toddlers are able to climb in and out as the chair remains stable. It’s simple to recline, and does so smoothly. The quality is great especially for the price point
